A general-purpose compound Chinese herbal medicine immune enhancer for freshwater cultured fish

Abstract

The invention relates to a general-purpose composite Chinese herbal medicine immune enhancer for freshwater cultured fish, which is made of raw materials with the following weight ratios, based on the amount added per ton of feed: rhubarb 800-2000g; Sanqi 350-1000g; water Silybum 1200-2500g; Cassia 600-800g; Astragalus 600-2000g; Scutellaria baicalensis 500-900g; 500-1500g; Garlic 1000-2000g. After many tests in the laboratory, it has been proved that the general-purpose compound Chinese herbal medicine immune enhancer for freshwater aquaculture fish can improve the survival rate of a variety of freshwater aquaculture fish in the process of attacking viruses; The long-term breeding experiment of farmed fish feed proves that the general-purpose compound Chinese herbal medicine immune enhancer for freshwater farmed fish can effectively reduce the incidence of a variety of high-density farmed freshwater fish and improve the survival of the breed; the additive is safe, efficient, and has no side effects for long-term use. The breeding objects have strong vitality, rapid growth, bright body color, high feed conversion rate, and good breeding benefits.

Description

technical field [0001] The invention relates to a feed additive, in particular to a general compound Chinese herbal medicine immune enhancer for freshwater cultured fish. Background technique [0002] China is the world's largest aquaculture country, and it is also the only country in the world where aquaculture output exceeds fishing output. The output of aquaculture aquatic products accounts for 70% of the world's total, and aquaculture occupies a very important position in the national economy. In recent years, my country's aquaculture industry has developed rapidly, and the average annual growth rate of freshwater aquaculture, as the farming model with the largest output, has remained stable at a relatively high speed of about 10%. In 2008, the total production of freshwater products in my country reached 22.973 million tons, of which the production of freshwater aquaculture was 20.725 million tons, accounting for 90% of the total production of freshwater products in my ...

Problems solved by technology

However, due to the deteriorating water quality of the aquaculture water body in recent years, the increasing density of large-scale aquaculture, coupled with the use of some inferior artificial compound feeds and the influence of incorrect breeding, feeding and medication habits, various diseases of freshwater aquaculture fish have broken out. It is becoming more and more frequent, resulting in increased mortality, slow growth, reduced vitality, and reduced feeding of farmed fish, which seriously affects the breeding profits and farmers' enthusiasm for farming. This situation seriously hinders the freshwater fish farming industry and further development of feed manufacturing
